CVE-2013-0153 – kernel: xen: interrupt remap entries shared and old ones not cleared on AMD IOMMUs
https://notcve.org/view.php?id=CVE-2013-0153
The AMD IOMMU support in Xen 4.2.x, 4.1.x, 3.3, and other versions, when using AMD-Vi for PCI passthrough, uses the same interrupt remapping table for the host and all guests, which allows guests to cause a denial of service by injecting an interrupt into other guests. El soporte de Xen para AMD IOMMU en v4.2.x, v4.1.x, v3.3, and otras versiones, cuando usa AMD-Vi para el paso por el PCI, usa la misma tabla para el trazado de interrupciones por el host y los anfitriones, lo que permite a los invitados causar una denegación de servicio por medio de la inyección de una interrupción en los otros invitados. • http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00021.html http://lists.opensuse.org/opensuse-updates/2013-04/msg00051.html http://lists.opensuse.org/opensuse-updates/2013-04/msg00052.html http://lists.opensuse.org/opensuse-updates/2013-06/msg00049.html http://osvdb.org/89867 http://rhn.redhat.com/errata/RHSA-2013-0847.html http://secunia.com/advisories/51881 http://secunia.com/advisories/55082 http://security.gentoo.org/glsa/glsa-201309-24.xml http://www.deb •

https://notcve.org/view.php?id=CVE-2013-0152
Memory leak in Xen 4.2 and unstable allows local HVM guests to cause a denial of service (host memory consumption) by performing nested virtualization in a way that triggers errors that are not properly handled. Consumo de memoria en Xen v4.2 que permite a los huéspedes virtualizados inestable locales que pueden provocar una denegación de servicio (consumo de memoria de host) mediante la realización de virtualización anidada de forma que provoca errores que no manejan adecuadamente. • http://secunia.com/advisories/55082 http://security.gentoo.org/glsa/glsa-201309-24.xml http://www.openwall.com/lists/oss-security/2013/01/23/8 http://www.securitytracker.com/id/1028032 • CWE-399: Resource Management Errors •
CVE-2013-0231 – kernel: xen: pciback DoS via not rate limited log messages
https://notcve.org/view.php?id=CVE-2013-0231
The pciback_enable_msi function in the PCI backend driver (drivers/xen/pciback/conf_space_capability_msi.c) in Xen for the Linux kernel 2.6.18 and 3.8 allows guest OS users with PCI device access to cause a denial of service via a large number of kernel log messages. NOTE: some of these details are obtained from third party information. La función pciback_enable_msi en el controlador PCI backend (drivers/xen/pciback/conf_space_capability_msi.c) en Xen para Linux kernel v2.6.18 y v3.8, permite que los usuarios de los sistemas operativos huésped (guest) puedan provocar una denegación de servicio a través de un número elevado de mensajes de log del kernel.
